Non-portable path to file:when building project for linux

anonymous_user_ba66b633 · March 19, 2018, 1:43pm

What i have:

Windows PC
UE 4.19 compiled from sources
Our Project whitch we want to build (Windows Clinet and Linux Dedicated Server)
Toolchain: v11 clang 5.0.0-based - for UE4 4.19

Windows clinet builds successfully. But Linux Dedicated Server not:

It worked well on UE.4.18 and Toolchain v9 clang 4.0.0-based

Hello,

We’ve recently made a switch to a new bug reporting method using a more structured form. Please visit the link below for more details and report the issue using the new Bug Submission Form. Feel free to continue to use this thread for community discussion around the issue.

Thanks

Fixing the case in your includes should solve this problem.
Possibly [-Werror,-Wnonportable-include-path] was not set in the v9 toolchain, so you could also try to switch if off again, but adjusting the includes is probably the cleaner soluiton.

anonymous_user_ba66b633 · March 19, 2018, 11:36pm

The problem is not in my includes but in generated engine includes

But thank you for “[-Werror,-Wnonportable-include-path]” i will try it.

Flash7 · March 31, 2018, 7:21pm

Has anyone solved that problem??? I’m having the same exact issue with 4.19 and clang 5. Any ideas?

anonymous_user_ba66b633 · April 2, 2018, 11:39pm

The only way i found is to disable “-Werror” in engine.
To do this change LinuxToolChain.cs:315

-Result += " -Wall -Werror";
+Result += " -Wall";

Flash7 · April 3, 2018, 1:59am

Awesome! That did the magic!

Flash7 · May 2, 2018, 3:09pm

Bump.

4.19.2 - the issue is still there. Have to do workaround with modifying LinuxToolChain.cs

Flash7 · May 2, 2018, 3:12pm

I remember reporting it in bug report form, but it looks like never made to the report in issues.unrealengine.com

anonymous_user_ba66b633 · May 3, 2018, 12:12am

I reported it too. Seems like it didn’t pass the premoderation.

Flash7 · May 3, 2018, 12:13am

I guess we keep bumping it, so someone from Epic notice it.

anonymous_user_0ce3d2c6 · November 19, 2018, 11:57am

Removing the “-Werror” from the ToolChains arguments seemed kinda too much to us, so we suppressed only this warning by adding

Result += " -Wno-nonportable-include-path";

to the LinuxToolChain.cs somewhere (below " -Wall -Werror") in GetCLArguments_Global. Note that this is only recommended if you cross-compile. When building for linux on linux, you probably want the build to fail and fix the underlying issue.

(using UE4.20 - v11_clang-5.0.0-centos7)

anonymous_user_614c8bfd · December 3, 2018, 10:53pm

Note you’ll also need to recompile UnrealBuildTool after making this change.

Flash7 · December 3, 2018, 10:57pm

you might need to recompile the engine. At least this is what I do: download the latest engine, change LinuxToolChain.cs, compile the whole thing.
